During the new crown pneumonia epidemic, fully guaranteeing the circulation of emergency supplies is the prior condition to keep the production life running smoothly and orderly. This paper established the architecture of an emergency material vehicle transportation system based on an intelligent logistics system to realize the transparency of logistics information. It also monitored road congestion in real-time based on Baidu map, combined the kernel of the brainstorming algorithm, solved the vehicle dispatching model of emergency materials with time window according to the real road network model, and simulated its path planning scheme using Matlab tools combined with the actual geographic coordinates latitude and longitude of isolation points to realize the data interaction of emergency materials circulation process and real-time adjustment of vehicle dispatching scheme. The method improves the efficiency of emergency supplies transportation during the epidemic.
